Performance
Enterprise-class, wirespeed, branch office
or small workgroup managed Layer 2
10/100 switching with 8 10/100 ports and
flexible Gigabit uplink capabilities. Two
models are available: both have 8 10/100
copper ports. In addition, the
OfficeConnect Managed Switch 9 has a
built-in 10/100/1000 Copper Gigabit
Uplink while the OfficeConnect Managed
Switch 9 FX offers a choice of a built-in
100Base-FX port and an SFP slot that can
accommodate 1000BASE-LX and SX trans-
ceiver modules.
Security and convergence
Advanced security for network data and
the management traffic controlling a
network. User network login with IEEE
802.1x and RADIUS authentication,
provide secure network access control at
the edge of the network. Further
enhancing security, authenticated users
can be automatically placed into a specific
VLAN, restricting access only to the data
they need. Secure Shell (SSH) encryption
of login passwords, management VLANs,
and management station “trusted IP
address” lists help protect the network
from rogue management threats.
Furthermore, the switches support Power
over Ethernet on port 1, 2, 5 and 6. This
allows seamless integration of Wireless
Access Points and VoIP phones.
Network Control
Network management is available through
an embedded web and command line inter-
face (CLI), or via an SNMP management
station. Supported by the range of 3Com
management offerings including 3Com
Network Supervisor.
Key Benefits
3Com®OfficeConnect Managed
Switch 9 Family
• Advanced, enterprise-class,
managed compact Switch with
wirespeed performance and
flexible uplink options
• Full SNMP management,
advanced security and Power
over Ethernet support make it
ideal for enterprise branch
office or small workgroup
applications
• Small compact and fanless
design makes it suitable for
small offices or confined spaces
• Choose from two Gigabit uplink
models for copper or fiber (with
support for legacy or Gigabit
fiber)
DATA SHEET
3Com OC Managed switches provide
wirespeed 10/100 Fast Ethernet switching
specifically designed for small Enterprise
workgroup and branch office environ-
ments. This award-winning switch family
boasts advanced Quality of Service features
that can reduce the latency of packets
through the network, with specific traffic
prioritization improving the delivery of
converged data such as voice and high
quality video over IP.
The switch family has great deployment
flexibility, with two choices for Gigabit
uplinks. The most economical choice
(OfficeConnect Managed Switch 9)
provides a fixed 10/100/1000 Gigabit
copper uplink while customers who require
support for greater distances or legacy fiber
support can deploy the OfficeConnect
Switch Managed Switch 9 FX which offers
the choice of a built-in 100Base-FX port
and an SFP slot that can accommodate
1000BASE-LX or SX transceiver modules.
Security is of the utmost importance for a
network, and the OfficeConnect Managed
Switch 9 family is a strong contributor to
this for workgroups and branch offices.
IEEE 802.1x network login ensures all
users are authorized before being granted
access to any network resource. User
authentication is carried out using any
standards-based RADIUS server, avoiding
any proprietary authentication mechanisms.
3Com backs these products with a 3-year
hardware warranty and an Advanced
Hardware Replacement policy.
